Folliculitis refers to an infection in a hair follicle, a skin opening containing the hair root, in the form of itchy and tender pustules and papules. It can affect people of all ages. Folliculitis on vagina would appear like a small pimple filled with pus at the base of the vagina (though not to be necessarily regarded as a sexually transmitted disease), and is usually accompanied with symptoms like itchiness, sores, pain and irregular discharge. There could be scientific causes attached to folliculitis or bumps on the vagina in the form of sebaceous cysts. These are generally harmful and may disappear after sometime. Folliculitis on vagina can be cured through antibiotics or injection of the appropriate drug.
